The aging effect on male mating activity inDrosophila melanogaster

  • Kazuhiko Kosuda


Noncompetitive mating activity for young (3-day) and old (28-day) Drosophila melanogaster males was measured under chromosomally homozygous and heterozygous conditions. Old males were consistently less active than young ones under both conditions. Three of 29 homozygous lines exhibited sterility due to aging. Virility at the old age did not correlate with that at the young age. Differences among homozygous lines were highly significant for old and young males, indicating a genetic basis for the trait. Individual variation in “old” virility was shown to be much higher than that in young males.
